Answer:
<em>The probability of obtaining a score less than 60 is 2.28%
</em>
<em>It happens 2 out of 100 times.</em>
Step-by-step explanation:
If the mean μ = 80 and the standard deviation σ = 10, then we need to find the probability that an X value is less than 60.
Then we find

To find this probability we use the Z statistic.



This is the same as

We look for this value in the table for the normal distribution of right queue and we have:

<em>The probability of obtaining a score less than 60 is 2.28%
</em>
<em>It happens 2 out of 100 times.</em>
Answer:
-2.90625
Step-by-step explanation:
Given the polynomial function
P(x) = x^5-x^4+x^3-3
If c = 1/2
At x = c
P(1/2) = (1/2)^5-(1/2)^4+(1/2)^3-3
P(1/2) = 1/32 - 1/16 + 1/8 - 3
P(1/2) = 1-2+4-96/32
P(1/2) = -93/32
P(1/2) = -2.90625
Hence P(c) is -2.90625
Answer: A
